''They're crazy, they're crazy...

REBELS WITH A CAUSE.

July 7, 1987

MEXICO CITY — REBELS WITH A CAUSE. ''They're crazy, they're crazy.'' That is Mexico State Governor Alfredo Baranda's opinion of the political group that calls itself the Democratic Current. Mexico's ruling Institutional Revolutionary Party, known as PRI, is lashing out at the group of dissidents that is pressing for reforms in Mexico's electoral system. The Current is headed by Cuauhtemoc Cardenas, former governor of the state of Michoacan. Last week he said he would register himself as the PRI candidate for president. The Current has been calling for the government to end the system whereby the incumbent president handpicks his successor. The Institutional Revolutionary Party has not lost the presidency since it was founded in 1929.
